Is solar power generation a good trend now?

In recent years, the use of solar energy has developed rapidly. In the northern and western regions of China, the promotion and application of solar power generation is welcomed by local residents. In some economically developed countries, in order to protect the natural environment, more and more people use solar energy for lighting.

Some companies in Germany, Switzerland, Japan, and the United States are trialing a new type of battery that can act as a roof tile. The capacity of existing buildings and photocells in western Germany has reached 50 billion watts!

The areas that use solar cells as energy sources in China are generally relatively closed or nomadic areas. There is no power grid, transportation is inconvenient, culture and economy are relatively backward. However, solar installations are more expensive, and in order to save investment in promotional applications, smaller power supplies are usually used to drive household appliances.

In this way, only high-efficiency electrical appliances have practical value.

In China, although the utilization of solar energy cannot be called the world's largest, the amount of its application, the wide range, and the potential market demand have attracted the attention of many companies in the world; Today, some villages have used solar cells to drive pumps to irrigate crops. In some remote areas, solar cells are used as a power source for microwave relay stations. In some small mountain villages, each household uses solar cells alone as a power source for night lighting.

There is also a centralized power supply system that uses large-scale solar cells to form a camp.

According to the characteristics of solar power supply and the development of electric light source technology, the light source suitable for solar power supply can be selected according to the power of the lamp in the place where single lamp lighting is used.

Indoor lighting above W should use low-power metal halide lamps, and its specifications are 50W, 75W, 100W, and 150W. The luminous effect is greater than 80lm w.

T5 straight tube fluorescent lamp should be used in the range of 50W, and its specifications are 21W, 28W, 35W, 49W, and the luminous efficiency is greater than 90LM W.

3. T4 straight tube fluorescent lamp should be used between 10 and 20W, with specifications of 12W, 16W, 20W, and the light efficiency is greater than 60lm W.

T2 or T1 fluorescent lamps should be used for low wattage light sources below W, with a luminous efficiency of about 50lm W

In the popularization and application of solar power supply, among the electric light sources that are suitable for it, low-power metal halide lamps below 20W are still being developed, while the commercial semiconductor light-emitting devices (LEDs) have low luminous efficiency and high cost. Therefore, it is more appropriate to use low-voltage DC power supply for low-power rare earth energy-saving lamps instead of 5-60W incandescent lamps.

The form is very good, clean energy, no pollution, renewable, so there is no better new energy on the earth than solar energy.

State support. Policy tilt.

Can the trend be bad?

All that are clean energy have a future -- especially natural ones.

The outlook is promising.

In 2021, the National Energy Administration and local governments issued a series of documents to give strong support to the development of distributed photovoltaics. Under the policy push, China's industrial and commercial rooftop photovoltaic projects have also been promoted rapidly, and more points have blossomed. As an advocate and practitioner of industrial and commercial distributed photovoltaic policy, the relevant person in charge of Guangdong Nankong Power (hereinafter referred to as "Nankong Power") said that it has become the consensus of the whole industry that photovoltaic will usher in a blowout development in 2022.

With the support of policies, rooftop photovoltaic power generation will also usher in an explosion.

Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photogenerated volt effect at the semiconductor interface. It is mainly composed of three parts: solar panels (components), controllers and inverters, and the main components are composed of electronic components. Solar cells can be encapsulated and protected in series to form large-area solar cell modules, and then combined with power controllers and other components to form photovoltaic power generation devices.
